I have done this in troubleshooting an OSPF issue where we needed to immediately grab logs from a buffer that had only 
limited size when the adjacency reset due to a dead timer. If you have WildPackets OmniPeek analzyer its easy if you 
understand the protocol operations you need to filter on. I simply created a filter for the specific packet (in this 
case OSPF Master Bit). Whenever the analyzer would see the specific packet it would launch an executable file. I used 
SecureCRT's scripting language to have it log into the router and save off whatever show commands I needed. You can 
also have it syslog, snmp-trap, or send an email.
